Feb 7 We saw a couple storm slabs that broke in today's snow 4-6" deep, 10-30' wide, and we triggered one 3-4" deep wind slab, "remotely", from a few feet back on a small ridgeline. R2-D1. These slabs were very soft, F- to F hard. Photo: GNFAC

Toured the ramp today and observed an avalanche in hour glass. It was a soft slab that broke in some rocks near the top of the chute, it ran the entire length of the chute and the debris was fairly large (d1.5). The crown looked to be between 8” and 1.5 ft, and was about 30 ft wide.

After skiing Bradley's Meadow, we skied north into Wolverine Bowl aiming to go up the backside of Texas Meadows. When we were in the large flat meadow to the north of Hourglass Chute we heard two avalanches come down from the ridge a few hundred yards north of Hourglass. Too low of vis to estimate size or see anything but the powder clouds come over the bottom cliffs.

In the Playground area of the Bridger Range, strong winds rapidly built wind slabs up to 25 cm deep around treeline. Skiers experienced a few cracks in this wind slab, propagating 2 or 3 meters from our ski tips. Photo: N. deLeeuw

Skiers triggered a small wind slab avalanche while skinning near the top of Pair Of Chutes in the Playground. The slab was about 1 foot thick, fist hardness, propagated 20 feet wide and ran 50 feet before breaking up and arresting. Photo: J. Taylor

Winds have worked over many slopes near the Throne. We found some slopes stripped nearly to dirt with the snow blown off to who knows where, and others had wind-sculpted sastrugi. Trees were broken off, and debris littered the snow surface. Photo: GNFAC

We triggered a small soft slab avalanche on a south facing aspect around 7800'. This avalanche broke in a wind drift, 4" deep in low density new snow, likely on a sun crust or near-surface facets. Photo: GNFAC

On 01/08 my partner and I skied into Frazier basin in the northern Bridgers, we skied the love chutes east down and overall the descent was pretty wind hammered from a downward wind. Once at the lake we took the Frazier return route where we found much better ski conditions in the corridor and decided to lap some of the features. We ended up triggering a small wind slab at around 8k on a NE aspect that broke about a foot deep and ran about 25 yards. Very dense wind slabs were forming on a lot of the aspects getting out of Frazier and we opted to not test our luck any further for the day.

Wind slab around 3-12" deep. NE aspect at 8,000 feet. Occurred sometime on January 8th.

A skier intentionally triggered an avalanche in Argentina bowl below south Saddle Peak. The avalanche broke 2 feet deep and ran 1000–2000 vertical feet piling debris 20 feet deep in the run out zone and breaking trees. Photo: anonymous

On Jan 5 With decent visibility we drove up Bridger canyon to Battle Ridge to look for recent avalanches. The most noteworthy was a slab 500'+ wide, 2'+ deep in Argentina Bowl (photo), 1 day old probably. Photo: GNFAC

Saw a small recent looking storm slab avalanche that appeared to be naturally triggered above the road on a south facing slope around 6000'. It ran all the way across the slope ~30' wide and ~4" deep within the recent snow. The snow didn't move far enough to reach the road. The slope was quite steep-- we didn't measure but I'd estimate 40*.

We triggered a wind slab. It propagated about 200 ft wide and was 3 ft at the deepest point. Interestingly on the edges and near the bottom (downhill side) of the slab it was only a few inches deep. It broke on the interface between the wind loaded snow and the light and dry snow we received a few days ago. Photo: A Shafer

Bottom of the Ramp, E aspect, 7900'. We found 24" of new snow which had nearly doubled the snowpack, leaving over five and half foot deep (HS 171) snowpack in this area. We got propagation (ECTP 24) at the storm snow interface. Photo: GNFAC

Avalanche in Hourglass chute above Wolverine. It looked to be triggered by an intentional cornice drop, was around 12 inches deep at the crown, 100' wide and ran 850' vertical feet. It looked around three days old.

The Last Word
On Saturday, February 8th, one skier was killed and a second injured in an avalanche in Utah (more information). This was the eighth avalanche fatality of the season. Our hearts go out to the victims' friends, families, backcountry partners, and the rescuers.
